Answer:

C x >=0

Step-by-step explanation:

Each term has to be defined

sqrt(5x) >= 0

Square each side

5x >=0

Divide by 5

5x/5 >=0/5

x >=0

sqrt(x+4) >=0

Square each side

x+4 >0=

Subtract 4 from each side

x+4-4 >=0-4

x >=0-4

The first is more restrictive so we use that

x>=0

A room has an area of 60 square meters and a perimeter of 32 meters. What are the length and width of the room?

Dominik [7]

Answer:

6 and 10

Step-by-step explanation:

xy=60

2(x+y)=32

x+y=16

y=16-x

Substitute y into area equation

x(16-x)=60

16x-x^2=60

x^2-16x+60=0

(x-10)(x-6)=0

x=10, 6

y=6, 10

The area of the continent of Susan America is about 6,888,000 square miles. Write 6,888,000 in expanded form using multiplicatio

Ilia_Sergeevich [38]

The area of the continent of Susan America which is 6,888,000 square miles can be written as 688* $10^{3}$ .

Given that the area of the continent of Susan America be 6888000 square miles.

We are required to express the area in the multiplication form by using the place values.

Area is basically quantity that expresses the extent of a region on the plane or on a curved surface.

Multiplication is basically finding the number which is product of two numbers.

6888000 can be written as 6888* $10^{3}$ which can be found out by the cube of 10 and multiply that by 6888.

Hence the area of the continent of Susan America which is 6,888,000 square miles can be written as 6888* $10^{3}$ .

solniwko [45]

Distribute the 3a^n to all the other values then solve...
(3a^n*a^n)+(3a^n*a^n)+(3a^n*-1)
4a^2n+4a^2n-3a^n=
8a^2n-3a^n

Find the net outward flux of f=a×r across any smooth closed surface in r3, where a is a constant nonzero vector and r=〈x,y,z〉

Paul [167]

Flux is zero since asked in $\pi$ is $0\pi$ .

Flux is the presence of a pressure field in a detailed physical medium or the glide of electricity through a surface. In electronics, the term applies to any electrostatic field and any magnetic subject. Flux is depicted as "traces" in a plane that contains or intersects electric powered fee poles or magnetic poles.

The definition of flux is a flow of liquid from the body, or a regular movement or exchange. An instance of flux is diarrhea. An example of flux is an ever-converting list of the responsibilities of a particular process. regular or frequent alternate; fluctuation.

Flux is a go-platform computer program that adjusts a show's color temperature in keeping with vicinity and time of day, offering practical respite for the eyes. the program is designed to reduce eye stress at some stage in night-time use, supporting reducing the disruption of sleep patterns.

Our field is IR^3 be,

F= (bz-cy,cx-az,ay-bx)

Now divergence theorem says that Flux can be calculated by

$\int\limits^ {} \, F.n = \int\limits^ {} \,( c.F) dv$

Now let's calculate the divergence of a vector field

F = (ia/ax + ja/ay + k*a/az)*((bz-cy)i+((x-dz))+(ay-bx)*k)

a/ax(bz-cy)+a/ay(cx-az)+a/az(ay-bx)

= 0+0+0

Flux is zero since asked in $\pi$ is $0\pi$ .
